Recreate the barplot below that shows the population of different continents for the year 2007.
Hints:
df_2007 = df[df['year'] == 2007]
fig = px.histogram(df_2007, x='pop', y='continent', color='continent',
text_auto='.2s', title='Population of different continents for the year 2007')
fig.update_yaxes(categoryorder='total ascending')
fig.update_traces(textposition='outside')
fig.show()
fig = px.histogram(df_2007, x='pop', y='continent', color='continent',
text_auto='.2s', title='Population of different continents for the year 2007')
fig.update_yaxes(categoryorder='total ascending')
fig.update_traces(textposition='outside')
fig.show()
Add text to each bar that represents the population
fig = px.histogram(df_2007, x='pop', y='continent', color='continent',
text_auto='.2s', title='Population of different continents for the year 2007')
fig.update_yaxes(categoryorder='total ascending')
fig.update_traces(textposition='outside')
fig.show()
Thus far we looked at data from one year (2007). Lets create an animation to see the population growth of the continents through the years
fig = px.histogram(df, x='pop',
y='continent',
animation_frame='year',
color='continent',
range_x=[0, 4*10 ** 9], text_auto='.2s',
title='Population growth of the continents through the years')
fig.update_yaxes(categoryorder='total ascending')
fig.update_traces(textposition='outside')
fig.show()
Instead of the continents, lets look at individual countries. Create an animation that shows the population growth of the countries through the years
fig = px.histogram(df,
x='pop',
y='country',
animation_frame='year',
color='country',
height=3000,
range_x=[0,1.4*10**9])
fig.show()
Clean up the country animation. Set the height size of the figure to 1000 to have a better view of the animation
fig = px.histogram(df,
x='pop',
y='country',
animation_frame='year',
color='country',
height=1000,
range_x=[0,1.4*10**9])
fig.show()
val_c = df.country.nunique()
fig = px.histogram(df,
x='pop',
y='country',
animation_frame='year',
color='country',
range_x=[0,1.4*10**9],
title='Popultion growth for the top 10 countries over the years')
fig.update_yaxes(categoryorder='total ascending')
fig.update_yaxes(range=(val_c - 10.5, val_c - 0.5))
fig.update_layout(showlegend=False)
fig.show()
